Adaptation of Multidimensional Existential Regret Inventory to Turkish: Reliability and Validity Analysis

Summary/Abstract: The aim of this study is to analyze the validity and reliability of the "Multidimensional Existential Regret Scale" (MDPS) in the Turkish population.The adaptation study was applied to people between the ages of 19-61. Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA) and test-retest reliability analysis were performed on two different study groups consisted of 343 people. As a result of EFA, a 34-item and a five-factor structure model, consisting of internal conflict, self-regret, regret of other persons, acceptance, sensuality, which explains % 55.93 of the total variance was obtained. According to CFA results the factor loadings ranged between .34 and .88. Model fit indices were found as RMSEA .070; GFI .803; AGFI .861; CFI .850; χ2 2.573 (p<.001). These values show that model-data fit is sufficient. The internal consistency reliability coefficient of the entire scale was .94. It was observed that the item-total correlations of the scale ranged from .34 to .74. The findings obtained from the research show that the Multidimensional Existential Regret Scale is a valid and reliable measurement tool that can be used in the field of psychology.
